Answer:
96000YEARS
Explanation:
Given that 1/28 = 8 half lives
this means that 8 half lives ,
and the given fossil should have 1/28 of the isotope
8 half lives = 1200 x 8
= 96000years
therefore the predicted Neandertal fossils is 96000years
Answer;
-Birth defects
Explanation;
In animals, long-term exposure to DDT can cause death or severe birth defects.
-DDT stands for dichloro-diphenyl-trichloro-ethane. It is an insecticide/pesticide previously used on crops. DDT has an adverse impact on many organisms such as crayfish, fish, shrimp, and other animals such as mammals.
DDT is slightly to moderately acutely toxic to mammals, including people, if eaten.Animals given potentially fatal doses of DDT develop liver lesions and those given DDT over a long period of time develop liver changes. In these animal populations DDT may cause birth and reproductive defects.
Answer:
6.75l l/min
Explanation:
Streptomycin is extracted from the fermentation broth using an organic solvent in a counter current staged extraction unit.
for 5 stage counter current staged extraction unit for streptomycin
X5 = 0.2g/l
X0 = 10.0g/l
X5/X0 = 0.02
given
Xn/X0, E, and
n = 5
A estimate of E can be evaluated directly;
E = 1.8
= LKd/H
by substituting the given values; Kd = 40, H= 150l/min
then we have,
L;L = 1.8(150)/40
= 6.75l l/min
Platelets would help the blood clot, therefore preventing blood loss. White Blood Cells would help protect against infection. So, I believe the answer would be platelets & white blood cells.
